The D application running under Win7 64 bit fails when exiting. The error

(Sorry, for the German!)

I tried to narrow the location of the failure and I suppose that the error occurs within gc_term(). If I omit this call the application ends without problems.

Why are you calling gc_term? It is function which shutdowns garbage collector (and deallocate everyobject). Doing it manually is really really wrong.

Hmm, but in the documentation (http://www.digitalmars.com/d/1.0/windows.html)
they do a call to gc_term() just before returning from WinMain().

BTW, this crash only happens on Win 7 64-bit - not on Win 7 32-bit.

Mass migration of bugs marked as x86-64 to just x86.  The platform run on isn't what's relevant, it's if the app is a 32 or 64 bit app.

Marking this bug as D1 only, as the OP used the example from the D1 Windows page (http://www.digitalmars.com/d/1.0/windows.html). This example doesn't even compile with D2.

On a semi-related note, the example in the D2 Windows page (http://dlang.org/windows.html) compiles and links just fine. I'm using Windows 7 64-bit.
